Loyalist expands Tully gold project east, west, and at depth

  Toronto, Ontario – TheNewswire – June 2, 2026 – Loyalist Exploration Limited (CSE:PNGC) (“ Loyalist ” or the “ Company ”) is pleased to announce its updated exploration thesis and a proposed conceptual diamond drill program totalling approximately 21,674 metres in 70 drill holes designed to test this thesis at its Tully Gold Project (“Tully” or the “Project”), located approximately 25 kilometres northeast of Timmins, Ontario. The proposed program has been designed to test the along-strike and down-dip extensions of known gold mineralization and to evaluate the potential to significantly expand the area currently encompassed by the Project’s historical mineral resource estimate (see below). The program will also assess the broader exploration potential of the Tully Project.

Program Highlights: Completion of a 3D magnetic inversion to refine the interpretation of key lithological contacts at depth   Step-out drilling to test east and west extensions of known mineralized zones   Down dip drilling to test depth extension and plunge of identified mineralized zones   Strategic infill drilling to increase geological confidence and data density in key target areas.   Targeting of mafic tuff units, which have demonstrated a strong association with gold mineralization.   Evaluation of structural controls and geophysical anomalies interpreted to be associated with gold mineralization.   The proposed exploration program is conceptual in nature and remains subject to financing, regulatory approvals, and the receipt of all required exploration permits. The program is expected to commence with a 3D inversion of existing high-resolution airborne magnetic survey data to further refine the interpretation of the contact between the weakly magnetic to non-magnetic hanging-wall sedimentary rocks and the strongly magnetic footwall ultramafic units. Building on the Company’s updated geological interpretation, a conceptual multi-phase diamond drilling program comprising approximately 21,674 metres in 70 drill holes has been designed to systematically test the exploration thesis and assess the potential to significantly expand the known gold mineralized footprint at the Tully Project.

Phase 1 (the “West Extension”) consists of 24 holes totalling approximately 7,913 metres designed to test the along-strike extension of gold mineralization to the west of the main mineralized zone. Phase 2 (the “East Extension”) consists of 22 holes totalling approximately 7,161 metres designed to test the along-strike extension to the east. Phase 3 (the “Deep” targets) consists of 24 holes totalling approximately 6,600 metres designed to test the down-dip and plunge extension of mineralization beneath the historical resource area.

Hole lengths range from approximately 125 to 700 metres, with collar dips ranging from approximately -47° to -80° and azimuths oriented to test interpreted mineralized structures. This initiative follows the Company’s recent engagement of P&E Mining Consultants Inc. to advance an updated Mineral Resource Estimate (“MRE”) for the Tully Project, prepared in accordance with the CIM Definition Standards on Mineral Resources and Mineral Reserves (the “CIM Standards”) and disclosed in accordance with NI 43-101. Subject to the successful completion of an updated MRE, the Company also intends to advance a Preliminary Economic Assessment (“PEA”) on the Tully Project.

Data generated from the proposed drill program (subject to timing) is expected to support these studies and to test for opportunities to expand the known mineralized footprint. Table 1: Summary of Proposed Conceptual Drill Program Note: Drill hole locations, lengths, azimuths, and dips are conceptual planned values only. Final hole locations and parameters are subject to change based on field conditions, geological observations during drilling, regulatory and access considerations, and Company priorities.

With strong geological indicators and a clear exploration model, we believe Tully has significant upside.”   About the Tully Gold Project The Tully Gold Project comprises a 458-hectare mining lease located in a well-established mining district with excellent infrastructure. It hosts a historical mineral resource estimate (not treated as current by Loyalist) of 107,000 ounces of gold (capped), comprising 358,000 tonnes grading 6.56 g/t Au (indicated) for 76,000 oz Au and 184,000 tonnes grading 5.17 g/t Au (inferred) for 31,000 oz Au, as estimated by Francis Minerals Ltd. and dated December 15, 2013. The estimate is not NI 43-101 compliant and has not been verified by a Qualified Person.

The project features numerous high-grade gold drill intersections and is advancing toward permitting, with additional exploration planned for 2026.   *Statement Regarding Historical Mineral Resource Estimates The Tully deposit historical Mineral Resource Estimate (“MRE”) is unclassified and does not comply with CIM Definition Standards on Mineral Resources and Mineral Reserves as required by NI 43-101. The MRE was taken from a report titled “Tully Deposit Mineral Resource Estimate” authored by Francis Minerals Ltd. and dated December 15, 2013. Investors are cautioned not to treat the estimate as current or rely on the estimate in making an investment decision.

The MRE is included herein to provide shareholders with background on the rationale for advancing the asset. A qualified person has not done sufficient work to classify this historical MRE as current mineral resources, and the Company is not treating this historical MRE as a current estimate. It is uncertain whether following evaluation and/or further exploration, the historical MRE will be able to be reported in accordance with NI 43-101. *Notes to Historical Mineral Resource Estimate 1.

CIM Definitions were followed for classification of Mineral Resources. 2. Mineral Resources are estimated at a cut-off grade of 2.5 g/t Au. 3. Mineral Resources are estimated at a gold price of $1,510/oz and a metallurgical recovery of 92%. 4.

High-grade assays are capped at 70 g/t Au. 5. Bulk density of 2.71 t/m³ was used. 6. Numbers may not add due to rounding.   Qualified Person Curtis Ferron, P.Geo.
